273 rocker help

Besides changing over to the lock nut style adjusters, the valve stem/tip oiling hole should be relocated. The old mopar perf books show a way of doing this.

Maybe its over kill - but what I did was buy 16 small allen head set screws and tapped the top oiling hole - later plugged them with the set screws and some red loctite. Next drill an 1/8" hole thru the body of the rocker arm, just under the arm of the rocker pointing towards the valve stem. Run a brake hone thru the center to clean any burrs and a quick file across the outside of the hole and you are done, clean and use them.

Get the Banana groove rocker shafts for improved oiling etc. You might also find the lock nuts may not sit flat on the rocker arm - you may need to dress this area flat with a sharp file. One other item, do not torque the lock nuts more than 25 ft-lbs, they will snap if you torque them too much - ask me how I know.
